USD/JPY Soars Post BoJ’s 0.75% Hike, Targeting 161.50 Resistance

The Bank of Japan has made a significant move by raising its short-term rate from 0.50% to 0.75%, marking the highest level in approximately thirty years, and this decision was reached by unanimous vote. Headline inflation stands at approximately 2.9%, with core inflation nearing 3.0%, significantly exceeding the Bank of Japan’s 2% target. Despite this, the Japanese yen has depreciated rather than appreciated. The USD/JPY experienced a notable increase of approximately 1.45% on the day of the decision, reaching around ¥157.7. It subsequently continued to explore the upper limits of its recent range, advancing toward the high-150s and testing elevated levels. The price response is straightforward: the market prioritizes the relative interest-rate gap and global capital flows significantly more than the symbolic nature of the first hike in decades. Despite the BoJ’s action, the rate spread compared to the United States continues to be significant. The Fed funds rate currently stands at 3.75%, whereas the BoJ is just reaching 0.75%, resulting in an approximate 300-basis-point edge for the dollar. In the case of USD/JPY, we observe a classic setup for a sustained carry trade: participants are taking advantage of low borrowing costs in yen to invest in assets that yield higher returns in dollars. As long as US policy stays in a “higher for longer” stance and the BoJ proceeds with gradual adjustments, there is a sustained structural demand for long USD and short JPY. A solitary 25-basis-point move from Tokyo does not alter the reality that, in relative terms, Japan continues to serve as the funding leg in global portfolios.

On the US side, the latest inflation and expectations data continue to provide fundamental support for the dollar. Headline CPI has moderated to approximately 2.8%, which at first glance appears manageable; however, one-year consumer inflation expectations have recently registered at 4.2%, marginally exceeding the consensus of 4.1%. The observed moderation in prices can be attributed to technical assumptions within the data, rather than indicating a straightforward, widespread decline in inflationary pressures. Markets have responded by extending the anticipated timing and magnitude of Fed rate cuts, with futures now reflecting fewer than two cuts throughout 2026, following a significantly more dovish outlook just a few months prior. The adjustment of the US curve supports the dollar aspect of USD/JPY, complicating the yen’s ability to gain from BoJ tightening. The broad dollar index has rebounded from its post-CPI lows and is approaching resistance around 98.75. Short-term flows and pre-holiday position squaring are evidently influencing the market, yet there exists a more profound narrative of persistent core inflation and heightened inflation expectations that supports stronger US yields. One group of investors perceives this as the onset of another upward movement in the dollar leading into early 2026; conversely, another group anticipates the index will decline to new lows once the current adjustment concludes. The implications for USD/JPY are clear-cut. A clean break above the 98.75 resistance band in DXY enhances the likelihood that the pair will re-test and possibly surpass the upper technical targets. Conversely, a failure at this level and a subsequent decline in the index would provide the yen with its first real chance to recover lost ground. Japan’s bond market indicates a shift in the Bank of Japan’s regime, although foreign exchange traders have yet to respond positively to the yen.

The yield on ten-year Japanese government bonds has reached approximately 2.018%, marking a near 20-year peak and exceeding the prior close by about 5.7 basis points. The change indicates a decrease in direct yield-curve control alongside an increase in market-based risk premia. However, when compared to US yields, Japanese paper appears relatively less appealing. The United States continues to present elevated nominal yields, frequently accompanied by superior real yields throughout a significant portion of the yield curve. The net result indicates that global fixed-income allocators perceive JGBs as less distorted than previously, yet still regard them as a lower-yielding option. For USD/JPY, this indicates that the upward pressure from the rate gap has diminished somewhat, yet it continues to favor the dollar distinctly.

The BoJ has positioned its action as a gradual, data-driven approach instead of signaling the beginning of an aggressive rate hike cycle. Governor Kazuo Ueda has emphasized the importance of wage momentum for the upcoming year as a crucial factor for potential increases, underscoring that the central bank will react to sustainable wage-price trends rather than temporary price surges. Simultaneously, the Japanese government is implementing a substantial fiscal package aimed at bolstering domestic demand, which poses the risk of establishing a higher baseline for inflation. The interplay of prudent monetary tightening alongside expansionary fiscal policy is indeed atypical. For USD/JPY, it indicates that although Japanese rates may gradually increase over time, they are not expected to narrow the gap with the US swiftly enough to alter the prevailing FX trend independently. From a technical perspective, USD/JPY continues to exhibit a generally bullish trend, even with occasional pullbacks. The pair is currently consolidating within a broad range; however, the price action remains above the 50-, 100-, and 200-day moving averages, indicating that the long-term uptrend is intact. The recent surge after the BoJ hike has driven the pair to a one-month peak, indicating that buyers continue to assert dominance whenever the market presents appealing entry points. Pullbacks have consistently resulted in higher lows instead of significant trend reversals, which is characteristic of a robust, yield-driven FX movement.

The market has established distinct resistance levels for USD/JPY, indicating potential upward movement. The initial resistance level is positioned at ¥157.80, a point where intraday advances have encountered obstacles and sellers are presently engaged. A daily close above that zone would serve as the initial confirmation that buyers are prepared to increase their bids and re-accelerate the trend. Furthermore, the subsequent critical level is around ¥161.50, a historically important peak that signifies the apex of the prior impulsive movement. A break and sustained close through 161.50 would effectively indicate that the bullish trend has re-established itself and that the pair is positioned to reach new cycle highs, provided the Fed–BoJ rate gap continues to be significant. On the downside, the initial significant support level is located around ¥154.50. The specified level has served as a local floor and a key reference for dip-buyers; a breach of this level would suggest a shift in short-term momentum, indicating that the market may no longer be inclined to purchase every dip. The subsequent key area is positioned near ¥151, coinciding with a structural pivot on the chart and the vicinity of the 100-day moving average. A decisive break under 151, particularly if paired with increasing yen demand and declining US yields, would serve as the initial credible technical indication that the multi-month bullish structure in USD/JPY is in jeopardy rather than merely consolidating. The momentum indicators support the positive outlook. The MACD is showing signs of a positive slope recovery following a consolidation phase, while the RSI is moving up from neutral territory without indicating any clear bearish divergences on the daily timeframe.

The combination of a trend above long moving averages, recovering momentum, and the absence of divergence is precisely what systematic trend followers seek when they choose to maintain or increase long positions instead of attempting to predict a peak. Given the current conditions, the most favorable trajectory for USD/JPY continues to be upward, with any pullbacks viewed as opportunities rather than reasons to exit the position. Seasonal liquidity conditions introduce an extra dimension of risk for those engaging in aggressive trading of USD/JPY. As the year concludes, balance sheets appear less burdensome, traders scale back their stock levels, and the available liquidity on either side of the market generally diminishes. The January 2019 flash crash in the pair serves as a notable reminder that abrupt, significant gaps can arise when a surge of order flow impacts a shallow market. Given that implied volatility remains relatively subdued in comparison to previous crisis periods, one could make a case for utilizing options to express directional views instead of relying on naked leveraged spot positions. Implementing defined-risk call structures to maintain a long position in the dollar versus the yen, or utilizing limited-risk puts for those anticipating a reversal, mitigates the risk of a sudden market shift during a holiday session that could deplete capital. The primary macroeconomic factor influencing USD/JPY continues to be the divergence in monetary policy. In the US, one-year inflation expectations stand at 4.2%. The persistence of core inflation and robust labor data maintain the Federal Reserve’s commitment to a prolonged period of elevated rates, resulting in fewer anticipated cuts and positive real yields. In Japan, the BoJ has recently adjusted to 0.75% after a prolonged period near zero, indicating a preference for gradual changes rather than swift normalization. The existing gap supports the carry trade, maintains the influx of international capital towards the dollar, and establishes the yen as an ongoing funding currency. Until that relative story changes – either through a sharper tightening cycle in Japan or a much more aggressive easing pivot in the US – the structural bias in USD/JPY suggests maintaining a bullish stance rather than anticipating a sustained recovery of the yen.
